Other than the usual handling and feature info, they measured some image quality parameters, taking care to say that it's a pre-production body. However, they were mightily impressed with the image quality and call the 5DII the "best and most versatile 'image maker' to date" (CI #308, page 138, upper middle column).

They also say that the noise/resolution couple is the best they got so far from any DSLR (I'm assuming they aren't talking about MF digital, only 35 mm and smaller chips).

CI does reproach a few shortcomings, among them the less solid build when compared to similar priced competitors or the modest AF module.

They're likely to publish the full test using a production body next month. I'll post an update in this thread if someone else doesn't beat me to it.

On a personal note, the 5DII looks more and more like the camera for me. Its weaker points aren't relevant for my subjects, and I seem to have gotten what I wanted most: high IQ, accurate AF (contrast), realistic price, reasonable weight.
